MILK-BOTTLE CAP.

Application filed March 2 lIy invention'ielates to improvements in milk bottle caps, and has for its primary object a milk bottle cap which is so constructposition of the A turther object is cap.

Fig. 5 is a section of a moditaken on the line 5-5 In the construction of my device Iemploy a cap which is composed oi a disk 6. This disk is preferably constructed of parafined material similar to the ordinary milk bottle cap. The disk 6 is provided with a pouring opening ranged air vent ever, being elongated. 6 is a disk 9 which has formed in its periphery, being of sufcient and a diametrically ar- 8, the pouring opening, how- Located on the disk a cutaway portion 10 this cutaway portion size so as to clear the opening 7. This is clearly illustrated in,I Fig. 2.

Diametrically 1() is formed a opposite the cutaway portion notch 11, which is adapted to register with the opening 8 when the cutaway portion 10 The disks gether by means registers 6 and 9 are pivotally secured towith the opening of a rivet or stud 12. The

stud 12 is provided with a head 13 over which is secured a disk 14. This disk is preferablyl of waxed paper.

being exposed This precludes any metal on the outside of the cap.

Secured to the underside of the disk 6 is a sheet 15 of parchment or waxed paper which extends over the bottoni edge of the rivet 12. This sheet precludes any possibility ot the milk or other liquid in the container con tacting with the metal, which might possibly cause the liqui consumption.

with openings 16 and 17, which register with the openings 7 and 8 respectively.

In Figures and 5 I have sho-wn a modified form ot construction in which a sheet of material 18, such as waxed paper or the like, is made in the term oian impertorate disk and secured to the bottom of the disk or cap 6. When my device is constructed in this manner, it is necessary, before the pouring operation can be commenced, to use a sharp knife and cut out that portion of the disk 18 underneath the opening 7 topermit the egress of liquid from the bottle, it being ,only necessary to use a toothpick or other sharp instrument to perforate the disk at the opening or air vent 8. In this way milk can be shipped any distance without any possibility of its contents becoming contaminated and upon arriving at its destination it is an easy matter to cut away the disk 18 at the openings without removing the cap and pour some ot the contents trom the bottle. Upon desiring to close the bottle, it is only necessary to revolve the valve 9 into the position shown in Fig. 1 when both the vent and pouring openings will be closed so that absolutely no. foreign matter or insects can get to the milk.

The present method of handling milk, especially in restaurants and similar places is to pushY one end of the cap down into the bottle, thus raising the other end and pour the milk. The usual practice then is to set the bottle with the tilted cap on a. shelf or some place where the flies find ready access and even where the cap is pushed back it is in constant contact oi the fingers with the cap which renders the same unsanitary for the reason that the milk being poured is bound to contact with the edges of the cap, which have been contacted with by the ingers, and milk being very susceptible to pollution will pick up any germs that might be on the lingers and lett on the cap by this repeated process of tipping or tilting the cap. Other caps have been devised with a liap which can be pulled outward and must then be pressed back inward again, but inall or" these devices the same danger of contamination is present.

In operating my device it is not my intention that the fingers ot' the operator shall at any time touch the valve 7 along the edges of the opening 10 but all swiveling or turning of the valve is to .be .accomplished Vby contact with ithe `notch 11 which7 acting only as an air vent or rather to uncover theair vent, doesnot come in contact with `:any of the dispensed milk,so in this respect all danger of contamination by contact with the lingers is eliminated.

My device can be as readily an ordinary milk bottle as is the present style otl paper cap, and in addition to the present paper cap, has all the advantages applied fto -of again closing up the bottle after aportion tioneddisk adapted to be rotated so as'to 1- open and vclose the openings in the first mentioned disk, and means carried by the undersurface of the 'iirst mentioned disk for covering said pivot.

2. A .milkbottle cap comprising a disk having a `pouring opening and an air vent .formedtherethrough, a second disk of less diameter `than the -Iii'st mentioned disk concentrically superimposed thereon a pivot for rotatably securing said disks together there being notches vformed in the periphery of `the second mentioned disk adapted to be brought into and out of register with Vthe openings in the 'first mentioned disk when the'second mentioned-dis'k-is rotated, and

means for covering .saidpivot so as to prevent the contents of the bottlefrom vcontactingV therewith.

3. A milk .bottle cap comprising afdisk having a pouring opening and a ventropening formedtherethrough, a second disk provided with cut-away portions concentrically located on one face of said first mentioned disk, a pivot passing thru the center of both disks so that sa'id second mentioned disk can be rotated and the cutaway portionsbe brought into coincidence with the openings in the irst mentioned disk whereby the contents of a bottle to 'which said cap is applied can bedischarged without removing said cap, and means ca'rriedbv the first mentioned disk for preventing the contact of the bottle contents with the pivot.

4. A milkbottle cap comprising a'd'isk having a pouring' opening and a vent opening formed therethrough, a second disk located on said Vfirst mentioned disk, a pivot for rotatably securing said disks together, said second mentioned end disk adapted during its rotation to open and close the pouring and vent openings in the first mentioned disks simultaneously whereby the contents ot a'bottle -to `which said disk is applied can be removed and protected-without removing' the rst mentioned disk, and a sheet of moisture=proof material secured to the inside of the first mentioned disk whereby contact 'between thepivot 4and lthe bottle contents is prevented.

In testimony whereof I have atiixed my signature.
